Denmark shut down airspace over Aalborg Airport overnight on 24–25 September after drones were spotted flying in the area. The incident mirrored a similar airspace breach in Copenhagen two days earlier. Reuters, Sky News, and the North Jutland Police confirmed the ongoing investigation.

Multiple drones seen near Aalborg Airport on 24–25 September

Northern Jutland Police reported that unidentified drones were observed over Aalborg Airport beginning at 21:44 on 24 September. The drones remained in the airspace until 00:54 on 25 September. Authorities stated that the drones were flying with lights on and that more than one was seen. They did not specify the type or quantity of drones involved.

Police coordination with national intelligence and military

Chief Police Inspector Jesper Bøjgaard Madsen of the Northern Jutland Police said that authorities were working closely with Denmark’s national intelligence agency PET and the armed forces. He added that efforts were ongoing to stop the drone flights and locate the operators.

“If we get the opportunity, we will take the drones down,” Bøjgaard stated.

However, police said it was too early to determine the intent behind the drone flights or who was responsible. As of the morning of 25 September, no suspects had been detained, and the drones had already left the Aalborg area.

Similarities to previous incidents in Copenhagen and Oslo

The flight pattern of the drones at Aalborg resembled the incident that had caused Copenhagen Airport to shut down on 22 September. The same day, Oslo Airport in Norway also closed its airspace for hours after a drone was seen overhead. Also on 22 September, a drone was observed over Malmö, Sweden.

Denmark’s Prime Minister said she could not rule out Russian involvement in the Copenhagen case, but no conclusions have been drawn publicly about the Aalborg drones.
